This course introduces the three major operating systems covered on the CompTIA A+ Core 2 exam — Windows, macOS, and Linux — with a focus on how each is installed, configured, and used in real-world IT support environments.
Learners benefit from building solid OS literacy across all three platforms, including how to navigate interfaces, manage files, and understand the foundational roles of power supplies and storage in a working system. Hands-on online labs put these skills into practice through guided, scenario-based exercises.

When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
